Greece's Prime Minister Alexis Tsipras is facing growing opposition from within his left-wing Syriza party.
They are against the conditions put forward by creditors for a continuation of the country's bailout.Many of Syriza MPs are against Athens' making any concessions.
Alexis Tsipras will brief parliament later following talks with the Troika of creditors- the EU, the European Central Bank and the IMF.
Greece has delayed Friday's 300 million euro debt repayment to the IMF. Earlier, it was agreed that instead of four instalments scheduled for June the country will be paying a combined single payment at the end of the month.
